Hi,
I dont think this will help as to why you are getting the .pak files corrupted message but it may show possibly which ones are getting corrupted.
I used this program Fastsum which is free to download and try at FastSum Download Page and had it calculate the checksum for the .pak files and displayed the results.
Touch wood I have not had this error so I am guessing that my .pak files are ok, I have copied the results into a text file for you to compare with yours at least then you may be able to see, if I am not mistaken which ones are getting corrupted as the checksum should be the same for each file.
There are two folders that contain .pak files
Steam\steamapps\common\Conan Exiles\Engine\Content\Paks
Conan Exiles_Engine_Content_Paks.txt (2.1 KB)
Steam\steamapps\common\Conan Exiles\ConanSandbox\Content\Paks
Conan Exiles_ConanSandbox_Content_Paks.txt (20.1 KB)
Maybe others could also do the same to be able to compare at least this way it is not such an unknown and may help narrow down which .pak files are causing the error.
From all intents and purposes this seems to be a random event and the only common link is Conan Exiles, yet this does not happen to all, is there another common link that can be found, some have mentioned graphics card and network drivers others have mentioned ssd drives, it led me to wonder if those players that are having this issue have another common link as in hardware or its associated drivers which are causing the problem.
Whilst you wait for Funcom to come up with a solution to this problem it may help for all players that are having this issue to compare the following to see if their are similarities
Graphics Card: Make, Model, Driver version, (Manufactures own Driver or Windows WHQL Driver)
SSD: Make, Model, Driver version, (Manufactures own Driver or Windows WHQL Driver)
Motherboard: Make,Model,Cpu,Network Adapter, Chipset, Latest Chipsets, Bios version and date
Are you playing other games that are using the unreal 4 engine if so what type of game and does it come up with the same message.
Are there any programs that are interferring with the running of the game either in the back ground such as an antivirus or as an overlay, like Steam overlay or Nvidia Experience, or streaming.
If there is a common thread through all of this other than the game itself this may be the problem causing the corrupt pak files and at least then a solution may be found.
